I took a few cuttings a few months back from an existing plant but didn’t know how old that plant was. Now my mint flowered and looks kind of old. Everywhere I read said to prune back before flowering. What can I do now?

You can still prune the mint and use the leaves if you wish. The flavor of this year's leaves may decline after flowering, but the plants will be good as new next year. Trimming back will help the plants be ready for winter. Also, mints usually spread easily so you might have more young plants next year. See this article:
